 performing, by the network equipment, a beam switch procedure that moves the communication from the first millimeter wave to a second millimeter wave transmitted between a user equipment and a first distributed unit of the distributed units based on an indication from the user equipment that the radio link interruption of the communication transmitted via the first millimeter wave has occurred and based on an expiration of the first timer due to a blockage of the first millimeter wave between the user equipment and a second distributed unit of the distributed units. 
 
     
     
       2. The method of  claim 1 , wherein the establishing comprises assigning the first timer and the first counter for a first detection of a first radio link interruption between the user equipment and the first distributed unit of the distributed units, and wherein the method further comprises:
 assigning, by the network equipment, a second timer and a second counter for a second detection of a second radio link interruption between the user equipment and the second distributed unit of the distributed units, wherein the expiration of the first timer or the second timer results in a determination that the radio link interruption has occurred. 
 
     
     
       3. The method of  claim 1 , wherein the respective resource configurations comprise a first resource configuration of the first distributed unit and a second resource configuration of the second distributed unit, and wherein the method further comprises:
 transmitting, by the network equipment, the first resource configuration to the first distributed unit and the second resource configuration to the second distributed unit. 
 
     
     
       4. The method of  claim 3 , wherein the transmitting is facilitated by a central unit communicatively coupled to the first distributed unit and the second distributed unit. 
     
     
       5. The method of  claim 1 , further comprising:
 prior to the performing, sending, by the network equipment, a coordinated report to the user equipment, wherein the coordinated report comprises the respective resource configurations and is customized for the user equipment. 
 
     
     
       6. The method of  claim 1 , further comprising:
 prior to the sending, determining, by the network equipment, the respective resource configurations for the distributed units. 
 
     
     
       7. The method of  claim 6 , further comprising:
 determining, by the network equipment, respective transmission nodes or reception nodes controlled by the first distributed unit and the second distributed unit. 
 
     
     
       8. The method of  claim 6 , further comprising:
 determining, by the network equipment, a beam forming capability of the user equipment, the first distributed unit, and the second distributed unit. 
 
     
     
       9. The method of  claim 6 , further comprising:
 determining, by the network equipment, a first network traffic load of the first distributed unit and a second network traffic load of the second distributed unit. 
 
     
     
       10. The method of  claim 6 , further comprising:
 determining, by the network equipment, a multi-connectivity configuration of the first distributed unit and the second distributed unit. 
 
     
     
       11. The method of  claim 6 , further comprising:
 evaluating, by the network equipment, a received radio link interruption report or a beam measurement report from the user equipment. 
 
     
     
       12. A system, comprising:
 a processor; and 
 a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
 transmitting respective indications of respective resource configurations to distributed units; 
 establishing a first timer and a first counter for detection of a radio link interruption of a communication transmitted via a first millimeter wave; and 
 performing a beam switch procedure for movement of the communication from the first millimeter wave to a second millimeter wave transmitted between a user equipment and a first distributed unit of the distributed units based on an indication from the user equipment that the radio link interruption of the communication transmitted via the first millimeter wave has occurred and based on an expiration of the first timer due to a blockage of the first millimeter wave between the user equipment and a second distributed unit of the distributed units.
